3.15 FMEC STM1E 1:1 Card
The ONS 15454 SDH FMEC STM1E 1:1 card provides front mount electrical connection for 2 x 12
ITU-compliant, G.703 STM1E ports. Ports 9 to 12 can be switched to E-4 instead of STM-1 (via CTC,
on the STM1E-12 card). With the FMEC STM1E 1:1 card, each interface of an STM1E-12 card operates
at 155.52 Mbps for STM-1 or 139.264 Mbps for E-4 over a 75-ohm unbalanced coaxial 1.0/2.3 miniature
coax connector. The FMEC STM1E 1:1 card is required if you want to use the STM1E-12 card in 1:1
protection mode or for connection to two unprotected STM1E-12 cards.
Figure 3-16 shows the FMEC STM1E 1:1 faceplate and block diagram.
Figure 3-16 FMEC STM1E 1:1 Faceplate and Block Diagram
You can install the FMEC STM1E 1:1 card in any EFCA slot pair (18/19, 20/21, 26/27, or 28/29) on the
ONS 15454 SDH. Each FMEC STM1E 1:1 card interface features STM1-level inputs and outputs
supporting cable losses of up to 12.7 dB at 78 MHz.
3.16 FMEC-BLANK Card
The FMEC-BLANK card provides EMC emission control for empty FMEC slots. It also provides a way
to close off the EFCA area, thus allowing air flow and convection to be maintained through the EFCA.
Figure 3-17 shows the FMEC-BLANK card faceplate.
You must install the BLANK FMEC in every empty FMEC slot to maintain EMC requirements of the
system and proper air flow.
